摘　　要：对我国大气中氧化亚氮的排放源及其大小进行了分析和计算,中国地区氧化亚氮的年排放置为950G_9N_2O-N,约占全球总排放量的6％.天然源和人为源各占我国氧化亚氮排放量的71％和29％.在天然源中以海洋排放为主,人为源中则以煤炭燃烧释放的贡献最大.计算显示今后几年内氧化亚氮排放的年增加量是6G_9N_2O-N.An analysis for N2O emission in China has been made. It was estimated that annual N2O-N N2O emissions over China are about 950 Gg N2O-N, which is 6% of the global sources, and that natural productions and anth ropogenic activities account for 71% and 29% of N2O annual emissions, respectively. Marine emission is the main part of natural productions, while stationary combustion of coal is the significant contributor to the anthropogenic sources. The estimate of net annual increase in atmospheric N2O source is roughly 6 Gg N2O-N.
